2002 to 2012 data from the Medium Resolution Imaging Spectrometer (MERIS) on ESA's ENVISAT satellite. The dataset provides 10-day aggregated maps of chlorophyll concentration for Lake Constance, developed by DLR-DFD and the GKSS Research Centre's Institute for Coastal Research. It was produced under the MAPP project for regional water quality monitoring.
Use Cases
- Analyze spatial and temporal trends in chlorophyll-a concentration across Lake Constance.
- Calibrate and validate water quality models using satellite-derived chlorophyll data.
- Monitor algal bloom dynamics and seasonal phytoplankton cycles from the 10-day composite maps.
- Correlate chlorophyll levels with other environmental parameters using the spectral data from 412-900 nm.
Strengths
- Data sourced from the MERIS instrument on ESA's ENVISAT satellite, a recognized mission.
- Provides 10-day aggregated composites, reducing gaps from cloud cover.
- Spatial resolution of 300 meters for detailed regional analysis of the lake.
Limitations
- Dataset was last updated in March 2010, with no recent data.
- Specific row counts, file sizes, and exact temporal coverage start date are not provided.
- Product generation depended on receiving and checking suitable MERIS data over the target water area.
